Bushy plant for West African biotope

[Kitalexander]

Hello I was watching this video and was wondering if anyone could identify the plants in it, especially the bushy one. It looks similar to Limnophila aquatica which is one of my favourite aquatic plants so I'm hoping someone can suggest a regionally correct substitute.

There are several possibilities, and probably many more, but in that area some endemics are Lagarosiphon madagascariensis and Lagarosiphon major are two that I'm aware of. And some others that look similar are Elodea canadensis, Egeria densa and Hydrilla verticillata. The problem is that these are all considered invasive in places that they are not endemic.
